Unfortunately this does not address the really important question, which
is "did he use directory indexing", i.e. was the partition mounted &
optimized with the dir_index option?

I don't think recommending razorfs is going to be very popular. Also it
doesn't address Windows (NTFS) at all.

Many factors come into account. Even just using ls on the big directory is
pretty much wrong because it tries to sort all files before printing them;
in contrast find|xargs often works just fine.

Not to rain on anybody's parade - I have completely replaced bdb with fsfs
everywhere with great success - but putting everything into 1 directory
was quite shortsighted, IMHO. :(
